Costa Rica — Tax: Tax Residency

The AI draft's core claim was backwards: Costa Rica does NOT tax residents on worldwide income — it operates a territorial tax system where only Costa Rican-sourced income is taxable, regardless of tax residency status. Foreign-sourced income (foreign salary for work performed abroad, foreign pensions, foreign investment returns) is exempt for both residents and non-residents. The 183-day threshold is more relevant to general residency/immigration status than to whether income is taxable, since taxability turns on the source of the income, not primarily on residency duration.

Why this matters

This is a significant correction: someone relying on the AI draft's 'residents are taxed on worldwide income' claim could wrongly believe they owe Costa Rican tax on their foreign pension or remote-work salary from a non-Costa Rican employer, when in fact that income is exempt under the territorial system. (Note: this does NOT affect US citizens' separate obligation to the IRS on worldwide income regardless of residence.)

Key facts

  • Costa Rica operates a territorial tax system: only income sourced within Costa Rica is subject to Costa Rican income tax.
  • Foreign-sourced income — a foreign pension, dividends/interest from foreign investments, or salary for work performed for a foreign employer — is exempt from Costa Rican tax, regardless of the taxpayer's residency status.
  • This means Costa Rican tax residency (unlike US tax residency) does not by itself create a worldwide-income tax obligation.
  • US citizens remain separately obligated to file and potentially pay US federal tax on worldwide income regardless of where they live, per US citizenship-based taxation — Costa Rican tax exemption does not affect this US obligation.
  • For individuals with Costa Rican-sourced income (a local job, a local business, local rental income), standard progressive income tax rates apply — see the Income Tax page.

Steps

  1. Identify the source of your income — Determine whether your income is Costa Rican-sourced (taxable) or foreign-sourced (generally exempt) — this, not primarily days-in-country, is what determines your Costa Rican tax liability.
  2. Confirm any home-country tax obligations separately — Costa Rica's territorial exemption for foreign income does not remove obligations to your home country's tax authority (especially for US citizens, who are taxed on worldwide income regardless of residence).

Required documents

  • Cédula/DIMEX or taxpayer ID (for those with Costa Rican-sourced income)

Common mistakes

  • Believing Costa Rica taxes worldwide income for residents — it does not; it taxes only Costa Rican-sourced income
  • Assuming exemption from Costa Rican tax on foreign income also exempts US citizens from US tax obligations — it does not
  • Focusing only on the 183-day threshold when the more decisive factor for Costa Rican tax liability is the source of the income, not days spent in-country
